I wanted this to be different from the other post I had about pools.

Has anyone saw or heard about a metal plate that gets installed in the "thru-wall" skimmer to satisfy sec. 680.26 of the NEC?

I also seen where there is a metal coupling attached to the pool motor just before the water enters into the pool filter. That is bonded to the grounding grid.

Yes Harold the plate gizmo exists. A local pool/spa store provided a sample for a 'look-see-feel' Shoot me a PM/Email for the name if you want it.

Basically, a curved metal plate & gasket with a bonding stud attached. Locate in skimmer, drill hole for stud & mounting hdwe, install gasket, etc.

It has a UL label.

I have not seen a 'pipe' with a UL label, but I have seen a lot of creative engineering methods to 'bond the water'.

For Harold and those others that may want to know...

Item is mfg by JM Products Inc, Canton Ma 02021

I don't have a web link yet, but Google may work.

Item is stainless steel with gasket & lug for 680.26. It is UL listed according to the cut sheet in my face.

Try www.bondsafe680.com

We have a local source here in the Twp I work in.

Greg, John,

I am home now and I was going to send John an e-mail. However I see that John posted a link to that product and I will go there after I read the rest of my messages. smile

Or.... Whats the problem with a brass coupling in the return line with a water main clamp? So long as it meets the sq in requirement.

Are all of our bond grids UL listed?
Does it need to be?
I've done and seen many bond grids not been UL.

I doubt a coupling would get you the sq/in but a short pipe nipple would.

Leland:
The UL label is required in most jurisdictions.

The pipe trick is accepted in some, as long as the clamp is listed/labeled and suitable for the application. An al clamp would not fly.

edit to embelish saome details.....

As there was no 'listed-approved UL' device available, the metalic pipe with a pipe clamp was acceptable. Now, that there is a listed/approved item, that is the method.

John,

My old supply house just saw an ad for a "bonding" nipple for above ground pools. They said it was invented by an electrician, however I don't know if it is UL listed yet. It looks like what Greg is talking about. A short nipple with a bonding lug on it. I haven't seen one yet, but looking forward to seeing one.
